From 6eb9dbf6a744f07b437e07e5f590625ebb7ab4cc Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Sat, 2 May 2020 21:46:42 +0200 Subject: [PATCH] linux-user, alpha: fix oldumount syscall When we try to bootstrap debian/lenny for alpha, it fails because it cannot umount /.root directory: ... Setting up initscripts (2.86.ds1-61) ... umount: /.root: Function not implemented dpkg: error processing initscripts (--configure): subprocess post-installation script returned error exit status 1 dpkg: sysvinit: dependency problems, but configuring anyway as you request: sysvinit depends on initscripts; however: Package initscripts is not configured yet. This is because, when we switched from syscall_nr.h to syscall.tbl, the syscall #321 has been renamed from umount to oldumount and syscall.c has not been updated to manage the new name. oldumount has been introduced in linux 2.1.116pre1 by: 7d32756b2 ("Import 2.1.116pre1") ... * We now support a flag for forced unmount like the other 'big iron' * unixes. Our API is identical to OSF/1 to avoid making a mess of AMD ...
